Drag and Drop

Having a display issue with a Drag and Drop content type.

Upon loading the H5P, it is displaying cut off on the right-hand side within Canvas.

If I click on the 'full screen' arrows in the upper right and then click on them to exit fullscreen, the H5P will display correctly.

This is happening on a Desktop inside Canvas using the embed code.
Browser: Firefox
Screenshots are attached.

I am using the picture Drag and Drop in a context where colour has very specific meaning.

Highlighting correct answers in green provides a misleading answer to students.

Can this highlighting be disabled?

Hiya, I've created an interactive video with a drag and drop exercise. When all the images have been dropped correctly into the right place, they have little crosses next to them.

I've searched h5p.org but can't find any guidance. Does anyone know why this might be?

Screen shot attached, thanks.
